Finally, in the 1980s, the National Christian Counselors Association founders Richard G. and Phyllis J. Arno.[7], after extensive research, identified a separate temperament, which they called Supine, which means “with the face upwards,” like a servant looking up to his/her master. The Arnos refer to it as “the serving temperament,” because the Supine “feels” that their only value is to serve others. Supines like and need people; however, they have a fear of rejection and do not initiate.
Supines are identified by strengths, such as a desire to serve, liking people, and having a gentle spirit. Their weaknesses include expecting others to read their mind (indirect behavior), harboring anger as "hurt feelings," and feelings of powerlessness. They are generally open to receiving affection, but have trouble initiating. Other profilers who use similar systems still refer to it as "Introverted Sanguine."
